In “Stormborn,” Sam discovers the cure for greyscale in a study of rare diseases by Archmaester Pylos — who died from greyscale, remember — and decides to test the method on Jorah, despite being forbidden by Archmaester Ebrose. In a scene *definitely* not meant for the faint-hearted, Sam *literally* chips away at Jorah’s greyscale in order to apply a salve to the skin under the greyscale. But because this is Game of Thrones, they aren’t just going to tell us there’s a cure, we’re obviously going to get a glimpse of the cure in the aforementioned book of rare diseases.

Essentially, the “cure” for greyscale is to simply cut it off.

But that doesn’t mean the salve isn’t super important to the healing process. The salve serves as the main antibiotic to treat the extensive wound left after the greyscale is cut away. As redditor firelark explained in a post, the salve, which is made from pine resin, the green bark of elder twigs, white beeswax, and olive oil would simply work to prevent infection and aid in the healing of the fresh skin.
